Abstract

A sound device includes a full-gamut single-body sound membrane, a voice coil, a dust cover, and an assembly structure. Materials of different kinds of beating degrees are applied at different positions of the sound membrane. A structural intensity of materials is changed radiantly, radially and gradually, from an innermost rim of the sound membrane toward an outermost rim of the sound membrane, such that the structural intensity gradually decreases from the innermost rim toward the outermost rim, to satisfy requirements of sounding for the full-gamut of audible frequency.

Claims

exact text as granted — not AI-modified
1. A sound device, comprising:
 a full-gamut single-body sound membrane; 
 a voice coil; 
 a dust cover; and 
 an assembly structure, 
 materials of different kinds of beating degrees being applied at different positions of the sound membrane, wherein 
 a structural intensity of materials is changed radiantly, radially and gradually, from an innermost rim of the sound membrane toward an outermost rim of the sound membrane, such that the structural intensity gradually decreases from the innermost rim toward the outermost rim, to satisfy requirements of sounding for the full-gamut of audible frequency, 
 wherein the sound membrane, integrally manufactured as a single body, includes at least a high-intensity fine-fiber membrane, a mid-intensity mid-fiber membrane, and a low-intensity coarse-fiber membrane, which are formed by changing the structural intensity of the material radiantly, radially and gradually, 
 further wherein the high-intensity fine-fiber membrane is made by high-intensity material of beating structure essentially based on a beating degree of Schopper-Riegler (SR)28° with a margin of SR5°, with the beating degree being adjusted to conform with the structure of the high-intensity fine-fiber membrane, and 
 further wherein the high-intensity material is chosen from hemp, flax, high-intensity chemical fiber or nano-grade chemical fiber. 
 
     
     
       2. The sound device according to  claim 1 , wherein a combination of the materials of the mid-intensity mid-fiber membrane and low-intensity coarse-fiber membrane includes animal fiber, plant fiber, chemical fiber, mineral, glass chemical fiber or carbon fiber. 
     
     
       3. The sound device according to  claim 1 , wherein the sounding is performed in an adjustable range of audible frequency, including the full gamut of audible frequency. 
     
     
       4. The sound device according to  claim 1 , wherein
 the inner rim of the sound membrane is integrally connected with the dust cover, and 
 a connection place is provided with the assembly structure which includes an inner ring and an outer ring, with bottoms of the inner ring and the outer ring being formed with an assembly slot for emplacing and assembling a top part of the voice coil. 
 
     
     
       5. The sound device according to  claim 4 , wherein a cross section of the assembly slot is in a shape of reverse V or reverse U. 
     
     
       6. The sound device according to  claim 1 , wherein the assembly structure is located at a top part of the voice coil and an assembly slot of assembly structure is assembled with an extension structure at a bottom end of the sound membrane. 
     
     
       7. The sound device according to  claim 6 , wherein the cross section of assembly slot is in a shape of V or U. 
     
     
       8. The sound device according to  claim 1 , wherein
 the sound membrane and the dust cover are assembled with an upper assembly part, and 
 the sound membrane and the voice coil are assembled with a lower assembly part. 
 
     
     
       9. A sound device, comprising:
 a full-gamut single-body sound membrane; 
 a voice coil; 
 a dust cover; and 
 an assembly structure, 
 materials of different kinds of beating degrees being applied at different positions of the sound membrane, wherein 
 a structural intensity of the materials is changed radiantly, radially and gradually, from an innermost rim of the sound membrane toward an outermost rim of the sound membrane, such that the structural intensity gradually decreases from the innermost rim toward the outermost rim, to satisfy requirements of sounding for the full-gamut of audible frequency, 
 further wherein the sound membrane, integrally manufactured as a single body, includes at least a high-intensity fine-fiber membrane, a mid-intensity mid-fiber membrane, and a low-intensity coarse-fiber membrane, which are formed by changing the structural intensity of the material radiantly, radially and gradually, 
 further wherein the mid-intensity mid-fiber membrane is made by mid-intensity material of beating structure essentially based on a beating degree of Schopper-Riegler (SR 23°) with a margin of SR5°, with the beating degree being adjusted to conform with the structure of the mid-intensity mid-fiber membrane, and 
 the mid-intensity material is chosen from sulfite pulp or kraft pulp. 
 
     
     
       10. A sound device, comprising:
 a full-gamut single-body sound membrane; 
 a voice coil; 
 a dust cover; and 
 an assembly structure, 
 materials of different kinds of beating degrees being applied at different positions of the sound membrane, wherein 
 a structural intensity of the materials is changed radiantly, radially and gradually, from an innermost rim of the sound membrane toward an outermost rim of the sound membrane, such that the structural intensity gradually decreases from the innermost rim toward the outermost rim, to satisfy requirements of sounding for the full-gamut of audible frequency, 
 further wherein the sound membrane, integrally manufactured as a single body, includes at least a high-intensity fine-fiber membrane, a mid-intensity mid-fiber membrane, and a low-intensity coarse-fiber membrane, which are formed by changing the structural intensity of the material radiantly, radially and gradually, 
 wherein the low-intensity coarse-fiber membrane is made by low-intensity material of beating structure essentially based on a beating degree of Schopper-Riegler (SR)18° with a margin of SR5°, with the beating degree being adjusted to conform with the structure of the low-intensity coarse-fiber membrane, and 
 the low-intensity material is chosen from wool, kapok or bullet-proof chemical fiber.
